In recent years, the practical use of laser displays has been advanced. Although the laser has many advantages, it is possible that speckle noise peculiar to coherent light occurs and the image quality of the display is greatly affected. Among various speckle noise reduction methods, we think that the exposure time of camera, which is observation means, is important in the method of temporally changing speckle noise patterns. In this presentation, we will report the development of speckle contrast measurement technique using a high sensitivity camera which can be captured the image in the exposure time close to the human eye response speed.
